Title: Overpressure exhaust system for air house
Inventor: CHOI BYUNG HACK
IPC: E04H15/20
Filed: 2018-02-01
Abstract: The present invention relates to an overpressure exhaust apparatus for an air house which is to be used as a gym or a warehouse or to grow crops or the like, and more specifically, relates to an overpressure exhaust apparatus for an air house, which may be fixated and installed on a wall at the entrance of an air house, comprising: a weight which is replaceable and movable; and an opening/closing door. When the internal air pressure in the air house is excessively high, the opening/closing door automatically opens by the air pressure. When the air pressure is recovered to a normal range, the opening/closing door automatically closes. Since the operation is conducted only through a physical driving means, the overpressure exhaust apparatus is able to open or be sealed purely due to the air pressure regardless of whether the power is supplied or not or whether there is a control means or not, and to have no error or malfunction of the apparatus. Since the overpressure exhaust apparatus automatically operates only when the internal air pressure in the house is excessive, and does not operate at normal pressure, the apparatus does not need to be separately maintained or managed for greater user convenience. In addition, the overpressure exhaust apparatus is able to adjust the opening force of the opening/closing door in accordance with an internal air pressure required by the air house, and thus the apparatus is available for all types of air houses, thereby providing very broad uses.
